Synergistical thermal modulation function of 2D Ti3C2 MXene composite nanosheets via interfacial structure modification

“…Larger interfacial spacing is characterized by XRD, but the more prominent aspect ratio characteristics make CNFs exhibit a structural synergistic merit in MXene. Figures 4 E and 4F demonstrate randomly oriented networks interspersed between nanosheets, which induces the bridging effect ( Figure 7 ) that can enhance the mechanical properties of composite films ( Jiao et al., 2021a , 2021b ) and create a thermal transfer path between nanosheets ( Badakhsh et al., 2019 ; Che et al., 2017 , 2018 ). Moreover, the order of addition in the preparation (adding CNFs in dispersed MXene nanosheets) also reduces the phenomenon of CNFs agglomeration ( Xiao et al., 2016 ).…”

“…As a member of 2D materials, the superior in-plane thermal conductivity of ∼2.84 W/(m·K) for pure MXene is reported ( Chen et al., 2018 ). The composite of MXene with various materials can further improve its in-plane thermal conductivity dozens of times, but the out-of-plane thermal conductivity of these materials is below 0.50 W/(m·K) ( Gao et al., 2021 ; Jiao et al., 2021a , 2021b ), which greatly inhibits the design of MXene as nTIM. Moreover, the out-plane thermal transport characteristics of MXene have not yet been fully understood.…”

Structural evolution of MXenes and their composites for electromagnetic interference shielding applications

“…[23][24][25][26][27][28][29][30][31][32][33][34] Although these composite materials possess merits such as light weight and good anti-corrosion performances, their shielding ability is modest and processing is difficult, which limits their use. [35][36][37][38][39][40][41][42] Due to their strong electromagnetic wave attenuation of electromagnetic waves, 2D materials with high conductivities have become the most competitive and promising shielding materials in recent years, [43][44][45][46][47][48][49][50][51][52][53][54] and MXenes are a representative example. [55][56][57][58] MXenes are a a new class of transition metal carbide materials with a 2D structure, made of nitride or carbonitride with the general formula M n+1 X n T x , where M denotes the early transition metal (for example, Mo, Ta, Zr, or Ti), X denotes nitrogen or carbon, and T x stands for the functional group located at the surface of the MXene.…”
